Application filed December 6, 1897. Serial No. 661,000. (No model.) i

To all whom, it may concern.-

Be it known that I, CHRIST J. LONNING, a citizen of the United States of America, and a resident of Paullina, in the county of OBrien and State of Iowa, have invented a new and useful Shingle-Nailin g Machine, of which the following is a specification.

The object of my invention is to provide means for driving nails in vertical planes, or in planes approximately at right angles to the plane penetrated thereby, and means for feeding the nails automatically to the drivin g mechanism and positioning said nails in proper alinement with the impact-hammer and in contact with the receiving object.

My invention consists in the combination of a nail-magazine, nail-driving mechanism, communication between the nail-magazine and the driving mechanism whereby the nails may travel to be driven, nail-feeding mechanism interposed between the magazine and driving mechanism and actuated by the drivlng mechanism, and means for transporting,

moving, and repositioning the apparatus conveniently and eifectively.

My invention consists, further, in the combination of a magazine designed to contain and feed nails in continuous order to a nailing mechanism, a nailing mechanism designed to receive said nails and individually positioning the same in a desired object, and stepby-step feedingmechanism designed to feed the nails individually to the driving mechanism.

My invention consists, further, in the combination, with a magazine and nail-driving mechanism, of a support and guide for the driven nail, comprising a base having a transverse notch in the lower edge thereof and a vertical bore or guiding-tube communicating with said notch, a pair of blocks mounted for lateral vibration relative to each other in said notch and provided with mating semiconeshaped grooves on their-inner faces, and yielding pressure devices engaging said blocks and limiting the lateral vibration thereof.

My invention consists, further, in the combination of a wheeled truck, a nail-magazine mounted on said truck, means for manually propelling said truck, and nail feeding and driving mechanism mounted on said truck and designed for manual actuation.

My invention consists, further, in the construction, arrangement, and combination of elements hereinafter set forth, pointed out in my claims, and illustrated by the accompanying drawings, in which Figure 1 is a side elevation of the complete machine. Fig; 2 is a plan of the nail-magazine detached from the machine. Fig. 3 is a sectional elevation of the nail-magazine 011 the indicated line 3 3 of Fig. 2. Fig. 4. is a plan of a hopper in which the nail-magazine is mounted, the cover thereof being removed. Figs. 5 and 6 are plan and end elevations, respectively, of the nail-feeding mechanism detached from the machine. Fig. 7 is a plan of the nail support and guide detached from the machine on the indicated line 7 7 of Fig. 1. Fig. 8 is a sectional elevation on the indicated line 8 8 of Fig. 7. Fig. 9 is a sectional elevation of the hopper and the guideway whereby the nails are fed from the magazine to the nail-feeding mechanism. Fig. 10 is a perspective of the gnideway and a deflector-plate detached from the machine. Fig. 11 is a vertical section showing the machine in use.

In the construction of the machine as shown the numeral 10 designates a base, on the ends of which are transversely positioned truckbars 11 12. Supporting-wheels 13 are mounted on the opposite end of the truck-bars 11 12 and are designed to rest and travel upon the surface into which the nails are to be driven. Standards 14 14 are mounted upon and rise from one end of the base 10, and brace-bars 15 15 are obliquely positioned and connect the upper ends of said standards with the opposite end of the base. Horizontal bars 16 16 are mounted on the standards 14 14 and brace-bars 15 15 and extend parallel with the base 10. A hopper 17, rectangular in plan view, is mounted upon the brace-bars 15 15 and extends upwardly therefrom, which hopper is provided with a hinged lid 16, secured by hooks 19 at one side. A handle 20 is mounted upon thelid 1S and is designed for manual securance to propel, lift, or otherwise move the'machine. A deflecting-plate 21 is mounted within the hopper 17, transversely thereof, and a series of slats 22, mounted within the hopper, connect the lower-edge of said plate with the rear side of said hopper, which slats are separated uniform distances to permit the nails to pass between the same, Fig. 4. An aperture 23 is formed at the convergence of the hopper-bottom and communicates with {a V-shaped guideway 24, which is mounted upon the brace-bars 15 15. The guideway 24 is formed in two sections A B, separated a slight distance to provide a slot 25, in which the shanks of the nails may travel, the heads of said nails being retained in the guideway by reason of the narrowness of the slot, as clearly shown in Figs. 6 and 9.

A nail-magazine 26 is provided and comprises a shaft 27, mounted for rotation by manual actuation in the sides of the hopper 17, heads CD, concentricallymounted on said shaft and formed in sections hinged together, a concavo-convex plate fixed to the lower sections of the heads, and a series of slats 28, fixed to the upper sections of the heads. The slats 28 extend at right angles to the slats 2'2 and are separated such distances as may be convenient for the passage of the nails. The concavo-convex plate 29 is imperforate and forms a bottom for the nail-magazine-when positioned as shown in Fig. 9. The hinge connection between the sections of the heads 0 D is formed by staples 30 31, positioned in overlapping pairs and connected by a traversing rod 32, having outturned ends, as shown in Figs. 2 and 3. Staples 33 34 are fixed to the upper sections of the heads, and hooks 35, fixed to the lower sections of said heads, engage said staples on the opposite side of the magazine from the hinges. An arm 36 is fixed to one end of the shaft 37 outside of the hopper and engages one or another of pins 37, mounted in and projecting outwardly from the adjacent side of said hopper, whereby the magazine is retained in a given position and rendered capable of varying degrees of adjustment to deliver nails to the hopper. Designating symbols or digits are imprinted on the side of the hopper adjacent to said pins to indicate the degree of adjustment or inclination of the magazine.

Standards 38 are fixed to the end of the base 10, opposite to the standards 14, and rise therefrom to a plane approximating to the handle 20, andahead 39 is fixed to said standards and projects toward the hopper 17. A bracket 40'is fixed to and connects the standards 38 and bars 16, and a cylinder 41 is vertically positioned between said bracket and the head 39, which cylinder is axially bored in a vertical plane. A bore is formed in the base 10 in alinement with the bore in the cylinder 41, and a notch is formed in the lower edge of said base in alinement with and extending on opposite sides from the said bore. Blocks 42 43 are mounted in the notch in the base 10 and have formed thereon flanges 44 44, projecting laterally from said base. Flat springs 45 46 are positioned on opposite sides of the base 10, traversing the aforementioned notch and blocks beneath the flanges of said blocks, and are confined by wires 47 48, secured by screws to said base, the said springs havinga limited degree of longitudinal movement in the loops formed by the wires. Mating grooves 49 49 are formed in the contacting faces of the blocks 42 43, which grooves are semicone-shaped, the upper end of the space inclosed by and comprising said grooves alining with and conforming in diameter to the bore, heretofore mentioned, in the base 10 and cylinder 41. The lower end of the space comprised by the grooves is normally of a diameter closely approximating to that of the nails employed by the machine and enlarges to the diameter of the heads of the nails to permit the passage thereof. The driving mechanism, heretofore mentioned, comprises a rod 50, mounted in the bores in the base 10 and cylinder 41 and guided for vertical reciprocation therein, and a handle 51, fixed to the upper end of said rod and designed for manual operation to actuate the said rod in vertical reciprocation. The handle 51 is provided with a bossed portion 52 and is preferably of metal to give the guiding mechanism an added weightto assist in the forcible impact with the nails. The nail-feeding mechanism, heretofore mentioned, comprises, in addition to the magazine and guideway, a carriage 53, having slide-bearings 54, mounted for travel on shafts 55 56, which shafts are fixed to the horizontal bars 16 16. Bearings 57 58 are fixed to the carriage 53 and have mounted for rotation therein a shaft 59, on which is fixed a wheel 60, which Wheel normally occupies a position such as that one side thereof may intersect the vertical plane of the rods of the driving mechanism. An expansive spring 61 is fixed to one end of the carriage and one bar 16 and exerts apressure on said carriage to hold the same normally in the path of travel of the driving mechanism. Pickingarms 62 63 are fixed to the carriage 53 and project below the same,which arms have horizontal portions in differenthorizontal and vertical planes parallel to each other and overlapping at their ends. The end portions of the picking-arms alternately traverse the slot 25 of the guideway and are so positioned as that one or the other thereof will obstruct the passage of the nails through said guideway at all times. The lower end of the slot in the guideway communicates with the bore .in the base 10. A deflecting-plate 64 is mounted obliquely transversely of and fixed to the guide- Way 24, and a notch is formed in said plate in vertical alinement With the slot 25 in the guideway.

In the practical use of my invention for shingling purposes a straight-edge is secured upon the roof, the shingles laid with their butts contacting with the upper edge of said straight edge, and the machine positioned With the wheels 13 on the lower side thereof engaging said straight-edge and resting upon said shingles. The nail-magazine is then located by manual actuation of the arm 36 in the direction of the arrow in Fig. 1, so as to incline said magazine and permit the passage of nails contained therein out of the slatted portion of the periphery thereof. As the nails are used the magazine is further adjusted to feed more nails, and when the machine is not in use said magazine is arranged to retain the nails. The magazine is held at any desired rotatable adjustment by engagement of the arm 36 with one or another of the pins 37. The operator grasps the handle with one hand and shakes the machine to precipitate some of the nails from the magazine into the hopper, which nails travel between the slats 22 along the hopper-bottom, through the aperture 23, upon the runway 24, and should assume positions depending through the slot 25 and travel to an engagement with and serial positioning above the arm 63, as shown in Figs. 6 and 9. At this time the operator grasps the handle 51 with his other hand and elevates said handle until the lower end of the rod rises above the wheel 60, as shown by dotted lines in Fig. 6, thus releasing the carriage 55 and permitting the positioning thereof, as shown in Figs. 5 and 6. The operator then forcibly depresses the handle 51 and rod 50, causing said rod to engage the wheel and propel the carriage against the resilience of the spring 61, resulting in a longitudinal movement of the pickingarms 62 63 across the slot 25, releasing the nails from engagement with the arm.63 and precipitating them upon the arm 62. The operator then elevates the handle and rod out of engagement with the wheel 60, the spring 61 propels the carriage in an opposite direction, the picking-arms again cross the slot 25, the arm 63 engages between the lower nail of the series and the nail adjacent thereto, and the lower nail of the series is released from the arm 62, travels along the slot, and falls along the bore of the base 10 to a position between the blocks 42 43, as shown by dotted lines in Fig. 1, in contact with the shingle into which it is to be driven. The operator then forcibly depresses the driving mechanism to a full stroke, engaging the head of the nail between the blocks 42 43 and driving said nail through the shingle and into the sheathing provided to receive the same. The operator then elevates the driving mechanism, as before described, moves the machine along the roof to the position where it is desired to insert the next succeeding nail, and continuously repeats the operation of driving and moving until the series of shingles are secured,
